Show HN: Semantica – Open-source semantic layer and GraphRAG framework (github.com)

Semantica, an open-source framework recently launched, aims to bridge the gap between chaotic raw data and AI-ready knowledge through a semantic layer and knowledge engineering systems. Designed for developers and organizations, Semantica transforms unstructured data—found in formats like PDFs, emails, and logs—into structured knowledge graphs. This is achieved through a three-layer architecture: an Input Layer for universal data ingestion, a Semantic Layer for advanced entity extraction and ontology generation, and an Output Layer that produces production-ready knowledge graphs, critical for powering applications like GraphRAG and AI agents. This initiative is significant for the AI/ML community as it addresses the common challenges faced in data management, such as disconnected data silos and inconsistent formats that often hinder AI model performance. Semantica automates the generation of formal ontologies, ensuring structured entities and validated relationships, which are essential for advanced reasoning in AI systems. With features like high-performance embedding generation and robust quality assurance processes, Semantica enhances the reliability of AI outputs, allowing for more effective decision-making and reducing the risk of errors typically associated with traditional AI systems.
